BINDER.

' Patented Oct. 22, 1907'.

Application tiled August 1l. 1906. Serial No. 330,232.

To all lwhom it may concern:

Be it known that I, FRED B. .I ORDAN, a citizen of the United States,residing at Winchester, in the county of Middlesex and State 'ofMassachusetts, have invented new and useful Improvements in Binders, ofwhich the following is a specification.

This invention relates to that class of binders ior holding loose leavesin which the leaves are impaled and held upon posts that are composed ofmembers, separably connected so that they may be parted for theinsertion or removal of leaves.

Heretofore such posts have usually been composed of members telescopingtogether; this is objectionable for the reason that such members havenecessarily been made of different diameters, and it has therefore beendifficult, if not impossible, to keep the edges of the sheets heldthereby in true alinement; difficulty has also been experienced inpassing the sheets over the post members of large diameter, while thepost members of small diameter have not held the sheets with suiiicientsecurity. i

A principal object of my invention is therefore to construct abinder-post composed of separable, slidably connected members which maybe parted for the insertion or removal of loose sheets, and which shallbe practically of equal diameter throughout; a further object of theinvention being to so construct the posts that the walls of the engagingapertures in the sheets shall be engaged by said posts or post membersat diametrically opposite points.

Still further objects of the invention are to simplify and improve thegeneral construction and operation of loose leaf binders.

vVith these and other ends in View which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being however, understood that no limitationis necessarily made to the precise structural details therein exhibitedbut that changes, alterations and modifications within the scope of theinvention may be made when desired.

In the drawings: Figure 1 is a perspective View showing the back and theside members of a binder frame constructed in accordance with theprinciples of the invention. Fig. 2 is a plan view of the same showingthe frame partly expanded. Fig. 3 is a plan view showing the framecontracted. Fig. 4 is a central longitudinal view of the frame. Fig. 5is a transverse sectional view taken on the piane indicated by the theother side of the frame.

line 5-5 in Fig. 2. Fig. G is a transverse sectional view taken on theplane indicated by the line 6 6 in Fig. 2. Fig. 7 is a longitudinalsectional view taken on the plane indicated by the line 7-7 in Fig. -2.Fig. 8 is a longitudinal sectional view taken on the plane indicated bythe line 8 8 in Fig. 2. Fig. 9 is a perspective detail view of one ofthe posts showing the post members separated. Fig. l0 is a perspectivedetail view showing the parts comprising one of the binder postsseparated from each other.

Corresponding parts in all of the figures are denoted by like charactersof reference.

The binder fra-me in its preferred form is composed of a back ,l andside members 2, 3, said back and side members may be constructed of anysuitable material;` castings of aluminium being preferred on account ofthe strength and lightness possessed by this material. The side membersare provided with side flanges 4, 4 and with end flanges 5, 5 the endflanges of the two side members being overlapped and in slidableengagement with each other so as to form a box like structure orframe. The back member 1 is provided with a centrally disposedupstanding boss G', said back memberl is also provided with pairs oflugs 7, 7 which are disposed longitudinally in alinement with eachother. The lugs 7 serve to support longitudinally disposed pins orshafts 8 upon which slides 9 are mounted.

The upstanding flanges 4, 4 of the side members 2, 3 are longitudiallyapertured for the passage of rods 1l, 12 which are partly exposedthrough undercut portions or recesses l0, 10 in the inner side faces ofthe upstanding ianges, so that the said rods will be supported inunobstructing positions The rod 1l,which is connected with the sidemember 2 extends through one ofthe end flanges 5 and has a non-circularterminal portion 13 adapted to be engaged by a key whereby it may berotated; said rod is provided with right and left-hand threaded portions14 that are exposed through the undercut openings 10, and upon saidthreaded portions are mounted nuts l5 having laterally extendL ing wings16; the rod 12 connected with the section 3 is smooth throughout, andthe portions of said rod that are exposed through the undercut recesses10 carry slides 17 having laterally extending wings 18, said slides andwings corresponding with the nuts and wings upon the threaded rod 11. Apair of levers 19 are pivoted upon a pin or fulcrum 20 upon the centralboss 6; these levers are disposed across one another, and the ends ofthe levers are connected by links or toggles 21 with the slides 9 uponthe longitudinal shafts 8, the pins or pivots 22 that connect the levers19 with the toggles 21 are also connected with the wings 1G of the nutsl5 at one side of the wings 18 of the slides 17 at The wings 16 of thenuts l5 and the wings 18 of the slides 17 extend through and beyond theundercut portions or recesses 3--3 in the inner side faces of theiianges 4-4, and the levers 19 and the links or toggles 21 may thus beconveniently connected with the nuts 15 and the slides 17 which move inthe said undercut recesses. By this construction the nuts, the slides,and the rods carrying the same are not only supported out of sight, butthey are disposed in sucha manner that they will not interfere with oiobstruct the insertion of leaves into the frame. The levers and thetoggles combine to form lazy-tongs that connect the side members 2, 3with each other and with the back member l.

It will be seen that under the construction described, by simplyrotating the right and left-hand threaded rod 11 the nuts 15 will travelupon said rod thus operating the lazy-tongs to expand or to contract thetrame according to the direction in which the nuts are moved, by movingthe side members 2, 3 apart from or toward each other as the case maybe, the slides 17 moving freely upon the smooth rod 12.

The upstanding flanges 4, 4 of the side members 2, 3 have beenillustrated as being provided at intervals with thickened or reinforcedportions 23 which are provided with recesses or countersinks 24 for theaccommodation of the heads 25 of the members of the binder posts. Theseposts P are composed of two separable slidably connected sections S, S,said sections being preferably of identical construction and dimensionsin order that they may be used interchangeably. Primarily each post maybe described as comprising a body which is preferably, although notnecessarily, of cylindrical shape; the circular cross section being themost readily fitted to correspondingly shaped apertures in the loosesheets that are to be bound; the body oi each post is longitudinally`divided into two members or sections adapted for slidable engagementwith each other, and each of these sections is composed of a pluralityof longitudinally disposed members 26 connected together at one end,which may be described as the outer end, by the heads 25, while theinner or engaging ends of said members are free and disconnected.Ordinarily each section of the post will be composed oi but twolongitudinal members as 26, but no limitation is made to this number;when the post, as is preferable, is of circular cross section, theindividual members 26 will obviously be of sector shaped cross section,and where each post section comprises but two longitudinal members, saidmembers will be diametrically opposed to each other so that each postsection will be provided with diametrically opposite segmental curvedbearing faces.

In the preferred construction of the posts, the heads 25 are providedwith suitable sector shaped apertures 27 in which the outer extremitiesoi the members 26 are seated and secured in any suitable manner; themeeting or engaging edges of the members 26 of each post section aredisposed practically in Contact with each other but they will readilyseparate sufficiently to enable the post sections to be assembled bysliding them together longitudinally as will be readily understood byreference to the drawings. The heads of the post sections may be securedin any suitable manner in the recesses or'countersinks 24 in theupstanding flanges of the side members of the binder frame; and saidupstanding side members 4, 4 are provided with apertures 28 or thereception of fastening members whereby the covers may be connected; saidcovers being readily detached from the flanges 4, when required, ior thepurpose of rebinding or when for any reason it shall be desired todetach said covers.

It will be readily seen that when the post sections are connected withthe side members oi the binder trame the posts will expand or contractwith said side members, thus enabling the binder frame to be readilyadjusted in such a manner as to securely clamp and closely engage theever varying number oi leaves.

The improved construction of the binder posts is simple, strong, durableand effective, and it enables the binder to be expanded from its closedposition to a position where its capacity will be practically twice thecapacity of the binder, when closed. By the improved construction of theposts as herein described said posts will be practically of equaldiameter throughout their lengths, and a very efhcient support will thusbe afforded the loose sheets, the walls of the apertures oi which willbe engaged by the post members at diametrically opposite sides.

Having thus described the invention what is claimed is:

1. In a loose leaf binder a frame having side members and a back member,rods supported in the side members, slides movable upon one of the rods,nuts engaging right and left-hand threads upon the other rod, lazy-tongsconnected pivotally with the nuts and slides and includingl leversfulcrumed upon the back member' of the frame, and slides supported bysaid back member and having pivotal connection with the lazy-tongs.

2. In a loose leaf binder a frame including a back and side members,said side members having undercut por'- tions or recesses, rodssupported in the side members and exposed through the undercut portions,slides engaging one of said rods, nuts engaging right and left-handthreaded portions upon the other rod, lazy-tongs connected pivotallywith the nuts and slides and including levers fulcrumed upon the backmember of the frame, slides supported upon and connected pivotally withthe lazytongs, and rods supporting said slides.

3. In a loose'leaf binder a frame including a back and side members saidback having a central boss and longitudinally disposed pairs of lugs,shafts or rods supported in said pairs of lugs longitudinally withrelation to the back member', slides upon said shafts, rods supportedlongitudinally in the side members of the frame, one of said rods havingright and left-hand threaded portions, slides and nuts engaging saidrods and having wings extending through undercut portions of the sidemembers, lazy-tongs connected pivotally with the wings of the nuts andslides and including levers fulcrumed upon the bosses of the backmember, and pivots connecting the togglcs of the lazytongs with theslides upon the shafts connected with and supported by lugs u pon theback member'.-

In testimony whereof, I aiix my signature in presence of two witnesses.
